The question is overdue,
you have a server with CentOS (64 RAM, 1TB, CPU 12), it dev (QEMU, LIBVIRT) Win2012R2 how much to allocate to this virtual machine?
Provided that it is one will be there to spin, nothing except it will not be installed.

In the Internet found nothing, except the driver's -balloon (ballooning KVM), which is the range (i.e. from 16GB to 32GB)
But how to launch it and tie to the VM? (also OFC nothing)
